In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Electron Donor-Acceptor Complex-Initiated Photochemical Cyanation for the Preparation of α-Amino Nitriles, published in 2020-12-18, which mentions a compound: 52287-51-1, Name is 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine, Molecular C8H7BrO2, Product Details of 52287-51-1.
An electron donor-acceptor complex-initiated α-cyanation of tertiary amines has been described. The reaction protocol provides a novel method to synthesize various α-amino nitriles under mild conditions. The reaction can proceed smoothly without the presence of photocatalysts and transition metal catalysts, and either oxidants are unnecessary or O2 is the only oxidant. The practicality of this method is showcased not only by the late-stage functionalization of natural alkaloid derivatives and pharmaceutical intermediate, but also by the applicability of a stop-flow microtubing reactor.
As far as I know, this compound(52287-51-1)Product Details of 52287-51-1 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
